Document Summary
Emotions develop early in childhood but difficult to identify emotions in infants. Rely exclusively on their facial expressions (affex system) Particularly difficult to differentiate among negative emotions. Smiling is the first clear sign of happiness. Meaning of infant smiles appears to change with age. During 1st month infant"s smiles are reflexive and/or caused by biological states rather than social interactions. By 2nd or 3rd month social smiles are directed toward people. 2 months infants laugh as well as smile during a variety of social and nonsocial activities. About 7 months infants start to smile primarily at familiar people rather than at people in general. Later in the first year children take pleasure in unexpected and discrepant events. By 2 children start to clown and around and are delighted when they can make other people laugh. By age 2 differentiating between infant"s anger and other negative emotions is no longer difficult. Often occurs in response to unfamiliar people.
